Hi

generally, as with any type of power semiconductor, you must verify that there are no short circuits between the power terminals, and obviously the command ones.

The correct procedure need to assume that you have the correct experience and the correct instrumentation to do it.Very often it is cheaper to use the ABB service that is equipped, prepared and can provide an adequate warranty on the replaced parts.

Have you tried to contact your local ABB sales network to get in touch with their service?They are very prepared and competent technicians.

Hi
I not have one specific procedure to send you. Have you unassemble the drive?
Have you verify in the power semiconductor are not in short circuit?

Also, in fairness, I am forced to ask you if you have the necessary electrical and security skills to carry out this type of operation.
As I have already told you, we advise against all users of ABB drives to make repairs themselves, as these require adequate preparation and instrumentation.
I do not doubt your skills, I'm just pointing to the established practice that is adopted in all parts of the world: to use the ABB Drives Service, one of the best assistance services that I know.
